Cable modems, like traditional telephone modems, are affected by spikes in electricity and data being transmitted through the cable line. The modem contains a cache, a chip that collects data before releasing it to your computer, that sometimes become overloaded with invalid data. This invalid data can slow down your cable modem's functions and prevent it from transmitting new data. To correct the problem, you have to empty your cable modem's cache. Once the cache is reset, your cable modem will return to a working state.
